To all whomz't may concern:

Be it known that I, HARRY L. KLINE,

a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certaln new and useful Improvements in Rotary. Internal-Combustion Engines, of which the following is a specification. 1

The invention relates to rotary internal combustion engines and the primary object of the invention is to provide a device of this character which is capable of being operated by an explosive mixture.

A further object of the invention resides in providing an engine in which a mainmum amount of power may be derived from a minimum amount offuel.

A further object of the invention resides in providing a device which is simple and durable in construction, not expensive to manufacture, and one which will be very eflicient in operation as well as very useful.

A further object of the invention resides in providing a device which will be positively operated, thereby insuring a proper timing of the working parts and eliminating any lost motion.

A further object of the invention resldes in providing a device wherein the gases are compressed and ignited before being admitted to the combustion chamber, said admission taking place at the best time to obtain a maximum amount of power from the explosion.

Vith these objects and others in view, the invention consists in the novel features of construction, combination of parts, and novel arrangement of the same, which will he more particularly pointed out in the claims.

In. the accompanying drawings forming a part of this application, Figure 1 is an end elevation of the completely assembled machine. Fig. 2 is a sectional view along the line 2 2 of Fig. 3. Fig. 3 is a plan view partly in section. Fig. 4c is a part section of the rotor along the line a d of Fig. 5. Fig. 5 is a plan view of the rotor. Fig. 6 is a section along the line 6 6 of Fig. 3. Fig. 7 is a part section of the easing along the line 7 7 of Fig. 2, showing the air admission openings in the casing.

Similar numbers of reference refer to similar parts throughout the several views.

The rotor I mounted on the shaft 2 is a close running fit on all sides in the casing. 3-, which forms the body or frame of the'machine, and is supported by the flanged base 4. e i

In the chambers 5 5 are hung the swinging pistons or gates 6 6 which area/close working fit within the casing The swinging gates or pistons 6 '6' are free to turn about the point 7 7. The .rollers 8 8 on the ends of the gates 6' 6 beanagainst the curved surfaces of the rotor 1, throughout the entire'revolution of the rotor.

In the chambers 9 9 are the slide valves 10 10, said valves being operated by the cam 11 on the shaft 2 through the medium of the levers 12 12. i i I The cranks 13 13 are secured to the portion of the swinging ates 6' 6 projecting through the casing, and are operated there. by, as shown by the dotted lines, causing the cranks 1 1 14L connected to the pistons 18 18 to reciprocate. The piston rods 15 15 are guided by the crossheads 16 16 which are in the form of pistons operating in cylindrical guides 17 17 Connected to the piston rods 15 15 are the pistons 18 18 operating in the cylinders 19 19. The pistons 18 18 are designed to draw the explosive mixture through the pipes 20 20, which are connected to any suitable form of'carbureter. (Not shown.)

Located at any convenient point in the chambers 9 9 are spark plugs of the usual design, connected with any source of suitable current, and with any suitable timing device. The spark plugs, coil, timer, etc., are not shown but the application of same will be readily understood in this instance. The operation of the machine is as follows:

Referring to Fig. 2:-The rotor 1 is about to reach the firing position, the direction of rotation being as indicated by the arrow. The swinging pistons or gates 6 6 are in the position indicated by the solid lines. The pistons 18 18 in the cylinders 19 19 have compressed a charge of explosive mixture and the chambers 9 9 are filled with this mixture under pressure. The explosion is timed to take place at the point in the revolution of the rotor where the edges 21 21 on the rotor 1 pass the points on the interior of the casing denoted by the numerals 22 22, and the slide valves 10 10 are opened at this point by the levers 12 12 operated by the cam 11, thus admitting pressure to the rear of the swinging gates or pistons 11 11, which swing out. The thrust of the rollers 8 8 bearing against the surface of the rotor cause same to revolve in the direction indicated by the arrow.

The exhaust takes place as soon as the i edges of the rotor l uncover the exhaust ports 23 23 as indicated by the dotted lines-showing the position of the rotor.

It is evident that as the rotor continues to revolve the'swinging gates or pistons 6 6 will be returned tothe former position by the pressure exerted on the rollers 8 8 by the surfaces of the rotor 1, and as soon as the original position is reached by the rotor another explosion takes place and the cycle cylinder 19 through the pipe 26 on each,

side of the engine.

Having thus described my invention, I

claim, and desire to protect by Letters Patent 1. In a rotary internal combustion engine the combination of a rotor means comprising a cylinder having flattened impulse receiving surfaces, a stator means having piston containing chambers, piston 'members' constituting gates hung in said stator means in such manner that the free or swinging ends bear or ride on the curved and flattened surfaces of the rotor means, a fuel supply means arranged to draw fuel and air from a carbureter and compress the mixture into the combustion chambers, slide valves with means of operating same arranged to admit the products of combustion to the power or working chambers after explosion.

2. In a rotary internal combustion engine, the combination of a rotor means, comprising a cylinder having flattened impulse receiving surfaces, a stator means having piston containing chambers with plston members constltutlng gates hung thereln, ports or openings in the casing of the stator means for the purpose of admitting air directly to the interlor of said casing for cooling purposes, and a means of cooling the combustlon chambers by a direct blast of air at each revolution of the rotor.
